To all whom it may concern:

Be it known that I, BARTON B. WARD, a subject of the Queen-of GreatBritain, residing. at New York, in the county of New York and StateofNew York, have invented a new tricalcircuitsillustrated in theaccompanying drawings in which- Figure 1, is-a side elevation of theentire apparatusshowing;part section. Fig. 2, is a side elevation of ashaft showing part cut" away, with wires for connecting commutator totransmitting arm of a shaftwhen more than one registering circuit isdesired leading from the same shaft.

of contact electrically insulated.

Similar letters-and figuresrefer to similar parts-in thedifferent views.

A, is'a-suitable frame and O, a rocking lever formingfa contact lever ofthe transmitterand attachedto a rock shaft H. Connectedto said rockshafts are one or more dash-pots 'D; D',,for the purpose of retardingthe movement of the circuit closing device as hereinafter described. Theend of the rock lever O,is-insulatedat O, and the lever makes contactwith contacts 13, B,.alternat-ely, the latter being suitably insulatedas shown and connected'to binding posts '1, 3. The contactrockinggleverO, is connected with binding post-2,- byattachment of awire leading from said post'to the conducting frame supporting thelever. SpringsS", S, hold the lever in central position.

0, is an eccentric heartshaped cam proj ect- .ing from the revolvingshaft .T, the movements of which are to beindicated or counted. Thesedevices constitute the transmitting part of the apparatus.

A" is a suitable frame carr in" electro magnets M,,M, which act upon anarmature Fig, 3, is a detail of'a rocking-arm showing its opposite sidesilever N,-to move the same in opposite directions against the action'of'centering springs K, K, are suitable registeringindicatorsoperateduponby levers L, L, which are acted upon by an arm 7:, extendingfrom the armature lever. Springs J, J ',return' the lovers of theindicator to normal position after they have been acted upon bytlie'armatur'e lever.

On the frame A, are binding'posts 4, 5, 6, connected to the magnets asshown.

G, is asuitable electric generator connected to binding post 4, andbinding post 2. Other connections are, as shown and as described in thedetail operation.

The parts supported by the'frame A, constitute the indicating orregistering part of .the apparatus.

When shaft T is revolved in a direction from right to left the cam 0coming in contact with the rocking arm 0 moves it in'tlie oppositedirection until it is enabled to pass it and --proceedon anotherrevolutiomin the mean time therocking arm 0 has assumed its originalposition, the upper end'ofit, which is in electricalconnection, has madecontact at 13 causing a current to-passfrom generator G' *in by way ofbinding post 2, as indicatedby arrows, through rocking arm 0, andcontact 13 and out by binding post 3 to binding post .6 and aroundmagnet m and out at binding post l, back to generator G thus formingacomplete circuit, through magnet in at each revolution of the shaftinthe direction'named. This establishing of current in magnet m attractsarmature N pivoted at a: causing its finger Z. to strike the lever Land-move it in a direction'to'register one on indicator K .the spring Jbringing the lever L back to the proper position for the next stroke,and the springs 'P and P cause the armature N to assume a centralposition, when the circuit is :broken at B and the rocking-arm0 is be-.ing centrally located by its springs S and S, and the-dash pots D and Dpreventing-a too rapid movement'or flying back of rocking arm 0 ormaking contact on the opposite side as the cam 0 leaves for the nextrevolution. As the shaft T revolves from left to right-a similar movingof the parts and functions performed is repeated only in the oppositedirection. The cam C of shaft T moving from left ICO to right causescontact to be made with rocking arm 0 at contact B closing the circuitleading around magnet on as indicated by the arrows, causing thearmature N to be attracted toward magnet m and against lever Lregistering one in indicator K, the parts assuming their originalpositions as described in the first instance, as the shaft proceeds onanother revolution. In the rocking arm 0 shown in Fig. 1, the lowerheart shaped part is shown insulated at o from the rest of the arm. Thisis to prevent electrical connection to the moving shaft; the same objectcan be accomplished by insulating the eccentric cam C from the shaft T.

In detail Fig. 3, is shown a rocking arm R with conducting sides Y and Yinsulated by Q), which if placed in similar relation to a revolvingshaft as rocking arm 0, Fig. 1, so that as the eccentric cam O which mayform part of the circuit, is rotated contact is made to either sideaccording to the direction of the shaft or body traveling in the planeto meet the arm and make the circuits as desired to register or indicateor perform things. A number of these circuit closing rocking levers orarms can be placed in the plane of rotation or movement of the same camO, and each close the circuit to separate registering or indicatingdevices.

Fig. 2, indicates a modification by which any number of eccentric camsC, may be attached to the same shaft T, and connected to a suitableelectric circuit each such cam acting upon a separate indicating orregistering apparatus. T, is the shaft whose revolutions are to becounted and NV, is a continuous con: ducting ring mounted on said shaftbut insulated therefrom and placed in connection with a source ofcurrent by means of a brush E, bearing on said rin 0, indicates one ofthe conducting cams which is connected with the ring W, or a conductorF. Current can thus be taken to or from the rotating shaft by the ring\V, and distributed to one or more eccentric cams which connect torocking arms and close the circuits of registering devices as described.These devices, obviously, might be multiplied as desired so thatcircuits carrying currents of different potentials might be carried overthe same shaft and operated by different or separate cams thereon.

The main object of this invention is to provide means for registering orindicating a reciprocating motion as for instance on a steamboat torecord and indicate in the pilot house the speed of the engine, and thedirection in which it is turning, a clock with a traveling dialpunctured or marked at each stroke or number of strokes of the engine,could be connected,and I do not confine myself to the exact method shownin registering and indicating as any indicator can be used that willshow the motion of the shaft or body in reciprocating motions.
